摘要：Fuzzy logic have been applied in many process and engineering applications to solve problems. In the case of control systems, where physical mechanisms are not well known due to high complexity and non-linearity, a fuzzy relational model may be useful. The aim of this paper is to propose the predicting the pa th loss with the field measurement models and represent them in a more convenient form for the proposed Fuzzy Logic modeling. This paper proposes method to predict path loss for cellular mobile communication systems using fuzzy logic. The propagation medium is classified in to several well-established propagation environments defined as a fuzzy set such as free space, flat area terrain, light vegetation terrain, heavy vegetation terrain, and village terrain. A unique mean path loss exponent (n) is assigned to each propagation environment, which is established by means of the experimental. Fuzzy logic is used to determine "n" number for an unknown environment , which will be obtained using linguistic rules that provide a fine-tuning of the known propagation environments. HATA model proposed by M. Hata has been used for the p resent analysis.
